JOSE SAMIERE, DECEASED, LATE OF NEW YORK, N. Y., 'BY MARIE SAMPEREPAUSAS, ADMINISTRATRIX, OF NEW YORK, N. Y., ASSIGNOR, BY MESNEASSIGNMENTS, T0 A. C. CHENEY PIANO ACTION C0., OF CASTLETON, NEW YORK.

SHEET-ADJUSTING APPARATUS.

To all whom t may concern Be it known that I, MARIE SAMPERE Parisi-xs, acitizen of the United States, and a resident of and whose post-officeaddress is the city, county, and State of New York, am theadministratrix of JOSE SAMPERE, deceased, late a citizen of the UnitedStates, inventor of certain new and useful Improvementsv inSheet-Adjusting Apparatus, of which the following is a specication,reference being had therein to the accompanying drawings.

My invention relates to improvements in sheet adjusting apparatus andhas part-icular reference to and is illustrated in the accompanyingdrawings in its application to a piano player.

This application is a divison of my previous application. Serial No.611396.

Referring to the ccompanying drawings Figure 1 is a froi t elevationpartly in sectionA of an apparatus illustrating an application of myinvention, and Fig. 2 is aY plan view looking down upon the `same withparts omitted.

5 is the outer framework in which the usual spools 6, and 7 are suitablymounted and upon which the tracker bar 8 is secured. One of these spoolsmay be driven in any suitable manner as by a chain 9 engaging thesprocketlO, secured to the shaft 11, provided with pinion 11 engagingthe gear 50 of the spool.

13 is a bracket in which the other end of the other shaft 6() may bemounted and from which it is forced rightwardly by the coil spring 14,said bearing being retained within the bracket 13 by any suitable meanssuch as the collar 15 held by the pin 16. At the opposite extremity ofthe shaft is mounted the arm 17. One end of this arm or bracket issuitably secured to the sha-ft 19 which is preferably bent at rightangles at the opposite extremity serving as a bearing 2O for the cam 21mounted within the bracket 22 secured to the frame 5. This cam issecured to the lever 23 bythe pin 24 so that as the lever 23 is moved,thecam 21 is moved within the bracket 22 thereby causing the shaft 19-to shift the spools 6 lright- Specication of Letters Patent.

Patented Dec. 19, 1916.

Divided andthis appIication filed December wardly or leftwardly. 'Thelever 23 is pivoted to the lever 25 which is pivoted to the pneumaticprovided with chambers 2(3--27 connected by the bar 2S.

29 and 3() are tubes connnunicating respectively with each of thechaiiilwn'sv 2Q lnd 27 of said pneumatic and the valve mechanism whichcontrols the action ol the same.

The action ot' my device is as follows: lVhen the sheet of music such as31 in passing from one roll to the other shifts laterally it actuates avalve which controls the How of air through the tubes 29 and 30 thuscausing the pneumatic to actuate, and through its connecting mechanismto shiftthe spool 6 in the opposite ldirection to thel direction inwhich the sheet 31 shifts. Thus the cam 21 is rotated by the levers 23and 25 when the pneumatic inflates or detiates and this shifts the bar19rightwardly or leftwardly and likewise the bearing (3() -to which thebar 19 is connected by the arm 17, thus shifting the spool 6. This isprovided for b v the coil spring 14 which projects the bar or bearing 60rightwardly against the collar 15, always under slight tension.

Of course it will be understood that various modifications may be madewithout departing from the spirit of the invention as claimed.

I claim:

In a device of the class described, a pneumatic, a spool bearing, aspool and sheet thereupon, a cam operatively connected between the barand said pneumatic, a tracker over which said sheet passesgandconnections between said bearing and said pneun'iatic and parallel withsaid spool 'which are adapted to shift pa 1allel with said spool andadjust said bearing when said pneumatic is operated, said spool providedwith resilient means to oppose longitudinal movement and said connectionprovided at one end with means adapted to be operated upon by said camactuated by said pneumatic.
